lierolibre is the project liberating Liero from all its proprietary components and to allow it to be distributed completely freely. “lierolibre” is a fork of 1.35b, and features a new nonproprietary sound pack. It sounds a bit funky but plays exactly the same way. Perfect for Richard Stallman and the likes of him. It is also easier to mod.
Liero the game description: http://en.wikipedia.org/wiki/Liero
”Liero is a video game for MS-DOS, first released by Finnish programmer Joosa Riekkinen in 1998. The game has been described as a real-time version of Worms (a turn-based Artillery game)。 It has many weapons and sounds from its precursor, MoleZ. 'Liero' is Finnish for earthworm and is pronounced [liero]. Later on, this game provided inspiration for the game Soldat.“
”In Liero, two worms fight each other to death for score (or frags) using a choice of five weapons from a total of 40 in a two-dimensional map. Most of the terrain, except for indestructible rocks, may be dug or destroyed by explosions. In addition to the weaponry, each player has a ninja rope which can be used to move faster through the map. This grappling hook-like device substitutes for jetpacks and can even latch onto the enemy worm to drag him closer to his foe. While playing, there are health power-ups to heal your worm. It is also possible to replace one of your five weapons by picking up bonuses. Before playing, you can select certain weapons to be available only in bonuses, in the entire game, or completely disabled. Unlike most side-scrolling deathmatch games, the weapons in Liero have infinite ammo. Key factors include the reload rate of each weapon and how fast they shoot, whereas in most others include how much ammo a gun sports and how frequent more ammo for that gun can be found. Liero depends all on timing and swift maneuverability. The gameplay mode can be deathmatch, Game of Tag or Capture the Flag. It can be played by two human players simultaneously in split screen or in a single player mode against the game's artificial intelligence, although the game's popularity is derived mostly from the fast-paced player-vs.-player action it provides.“
